Metallographic specimen preparation of thermal spray coatings is continuing to undergo intense scrutiny. From ASM to ASTM, efforts are being mounted to provide laboratories with metallographic procedures that produce accurate microstructures. The initial difficulties encountered by both groups were primarily related to identification of the true structure of coatings. As this issue is resolved, the secondary task of how to reveal the true structure on a consistent basis becomes crucial. The introduction of new machinery and consumable products into laboratories has transformed the art of metallography into a controllable process. A secondary, and perhaps, more profound effect of this shift has been the simplification of those processes. Yesterday`s methods were often composed of a multitude of steps. Additionally, these methods were coating specific, that is a different method for each coating system. Notable progress has been made towards a more universal method. In addition to being applicable to a wide range of coatings, this method is quite simple. The results of this new method will be presented as applied to a wide range of thermal spray coatings and other wrought and cast materials.
